Holby City's eighteenth series was produced by the BBC and aired its 52 episodes on BBC One in the United Kingdom. The series aired in the 8 pm timeslot on Tuesdays across the United Kingdom, except in Scotland, where the series has no fixed timeslot. Oliver Kent continues his role as the executive producer of the show, while Simon Harper serves as the series producer. In October 2015, Harper announced the show would receive a new opening titles sequence and the new sequence was first previewed in November 2015. The new opening titles sequence first aired in the episode, "In Which We Serve", broadcast on 1 December 2015 as the eighth episode of the series. Harper confirmed the series would feature a standalone episode, which would air in January 2016. The episode centres around junior doctors, Arthur Digby (Rob Ostlere), Morven Shreve (Eleanor Fanyinka), Oliver Valentine (James Anderson) and Zosia March (Camilla Arfwedson), and Harper confirmed that it would answer several "'will they, won't they?' questions". The episode, "Young Hearts, Run Free", aired on 5 January 2016 as the thirteenth episode of the series.
This series featured several crossover events with Holby City's sister show Casualty. Harper confirmed this series would feature crossovers with the show, especially around the time of Casualty's thirtieth anniversary. Guy Henry made three guest appearances as Henrik Hanssen in Casualty between January and May 2016, while Rosie Marcel guest appeared in a February 2016 episode of Casualty as her character Jac Naylor. On 28 June 2016, it was announced that Marcel, Henry and Alex Walkinshaw would guest appear in Casualty's feature-length anniversary episode "Too Old for This Shift" as their characters Jac, Hanssen and Adrian "Fletch" Fletcher respectively. Walkinshaw previously appeared in the serial as a regular character between 2012 and 2014. Marcel and John Michie, who portrays Guy Self, appeared in another episode of Casualty two episodes later.
On 27 August 2016, it was confirmed that Amanda Mealing would appear in an episode of Holby City as her character Connie Beauchamp. The actress previously appeared in the serial between 2004 and 2010. Mealing appeared in episode 47, "Protect and Serve", broadcast on 30 August 2016. Michael Stevenson and Lloyd Everitt also appeared in the episode as paramedics Iain Dean and Jez Andrews while Tonicha Lawrence guest starred as Steph Sims, a patient who appeared in Casualty. George Rainsford also appeared during the eighteenth series as his Casualty character, Ethan Hardy. Rainsford appeared for Ostlere's final scenes as Arthur Digby after they pleaded with producers to allow them to share a scene together.
In an interview with Daniel Kilkelly of Digital Spy, Harper revealed a selection of upcoming storylines to feature in the series. He explained that a "dramatic and exciting" twist in a storyline involving Cara Martinez (Niamh Walsh) and her husband, Jed Martinez (Jody Latham), would challenge Cara's relationship with Raf di Lucca (Joe McFadden), while a theme of "people's pasts coming back to haunt them" would be explored with the characters of Mo Effanga (Chizzy Akudolu) and Serena Campbell (Catherine Russell). He stated that Mo would re-evaluate her life and relationship with Derwood "Mr T" Thompson (Ben Hull) following the return of her surrogate son, whereas Serena would begin a relationship in a new storyline before her past is explored. Harper also announced plans to explore the on-again, off-again relationships between audience favourites Zosia and Oliver, Arthur and Morven, Sacha Levy (Bob Barrett) and Essie Harrison (Kaye Wragg), and Mo and Mr T, adding that they would answer some ongoing questions in late 2015. He also stated that Zosia and Oliver would be "caught in the crossfire" of Jac Naylor's (Rosie Marcel) rivalry with Guy Self (John Michie) following Guy's move to Darwin ward. Harper said that Sacha and Essie's relationship would be challenged by Essie wanting to have a child as well as Sacha's Jewish family being unable to overlook Essie's grandfather's Nazi background. Harper also expressed an interest in creating more nurse characters as he felt the show lacked nursing characters.
In February 2016, David Ames revealed that his character, Dominic Copeland, would be attacked. The storyline began in autumn 2015 when Dominic begins a relationship with patient Lee Cannon (Jamie Nichols), although he is "gutted" when Lee steals from him and disappears. Lee returns when his pregnant wife, Alison Jones (Elizabeth Cadwallader), is admitted onto Keller ward, where she discovers Lee and Dominic had a fling. Lee becomes aggressive and confronts Dominic in the staffroom. Ames explained that Lee is "furious with the fact his whole world has crumbled" so Dominic reminds Lee about his misdemeanours. The actor stated that when Lee grabs a knife, he creates a "tug of war" between them and someone is stabbed. The storyline is revisited in May 2016 when Alison is readmitted onto the ward, leaving Dominic astounded. Dominic helps Alison as she delivers her child, but he becomes enraged when Alison asks him to accompany her to visit Lee in prison. Ames said that Dominic warns Alison that "you can't hold on to the past", something which he has to remind himself.
Harper teased a "heartbreaking and touching" storyline to air in 2016 which would bring together every character. This storyline commenced in February 2016 when Arthur is tested as a liver donor for Morven's father, Austin Shreve (Clinton Blake). While testing, Essie discovers a mole on Arthur's back and believes it could be melanoma, however Arthur dismisses her claims as being "over-protective". Essie requests a second opinion from Hanssen, who orders for it to be removed and examined. Ostlere explained that Arthur "feels like the rug has been pulled out from under him" after his diagnosis. Off-screen, Ostlere raised awareness for melanoma, issuing his support during Melanoma Awareness Month. Arthur learns he has secondary tumours on his lungs, before discovering his treatment is not working and his cancer is terminal. The storyline concluded with Ostlere's departure from the show; on-screen, Arthur and Morven decided to travel together but before they can leave, Arthur collapses and falls unconscious. Since Arthur's cancer is too advanced, his life cannot be saved and he soon dies surrounded by his colleagues. Ostlere found filming his final scenes emotional and said he would miss playing the character.
